To determine how many images of the vowels of the capital English alphabets (A, E, I, O, U) look like their original shapes when seen in a mirror, we evaluate each vowel:
- A: The letter 'A' is vertically symmetrical, meaning that its mirror image looks the same as the original.
- E: The letter 'E' is not vertically symmetrical, so its mirror image does not look like the original.
- I: The letter 'I' is vertically symmetrical, meaning that its mirror image looks the same as the original.
- O: The letter 'O' is both vertically and horizontally symmetrical, so it looks the same in the mirror.
- U: The letter 'U' is vertically symmetrical, meaning that its mirror image looks the same as the original.
Based on this analysis, the images of these vowels 'A', 'I', 'O', and 'U' look the same as their original shapes in a mirror. Therefore, 4 is the correct number of vowels that maintain their original appearance in a mirror.
